This invention relates to mining apparatus and more particularly, butnot exclusively, to improved propelling mechanism for a coal miningapparatus of the Wheel mounted type adapted to operate While supportedon and guided by the mine traclvvay.

An object of this invention is to provide an improved coal miningapparatus. Another object is to provide an improved coal miningapparatus of the Wheel mounted type adapted to operate While supportedon and guided by the mine trackvvay and having improved propellingmechanisr Still another object is to provide an improved propellingmechanism for a mining apparatus ot the aforesaid character which issupplemental to the usual truck Wheel driving mechanism. Anotherobjectis to provide in a mining apparatus of the aforesaid character animproved haulage mechanism supplemental to the truck Wheel drivingmechanism for propolling the apparatus along the mine track- Way, thesaid supplemental haulage means being operable Wholly independently ofthe truclr Wheel driving mechanism. A further object is to provide animproved haulage means tor a mining apparatus of the Wheel mounted typeincluding a power Winding device and a cooperating draft element, thesaid haulage means supplementing the usual propelling mechanism for theapparatus. Yet another object is to provide an improved supplementalhaulage means for a Wheel mounted mining apparatus for propelling thelatter along the mine traclrway and including a plurality ofindependently operable'ivinding devices and cooperating flexible draftelements whereby the usual truck Wheel driving means may besupplemented. A further object is to provide a supplemental propellingmeans for a Wheel mounted mining apparatus and including a flexibledraft element connectible to an extraneous abutment whereby in case thetraetive effort of truck Wheel drive is insullicient to propel themachine with the necessary power, the same may be augmented or at timessupplanted by the improved supplemental propelling means. These andother objects and advantages of this invention will, however,hereinafter more fully appear.

In the accompanying drawings there is shown tor purposes of illustrationone form which the invention may assume in practice.

In these drawings,

Fig. 4 is an enlarged transverse vertical sec` tional view takensubstantially on line 4 4 oit Fig. 2 with parts shovvn in elevation.

In this illustrative embodiment of the invention there is shown a miningapparatus of the Wheel mounted universal type of the same generalcharacter as that disclosed in a copending application to one Morris P.Holmes, Ser. No. 137,600, filed Sept. 24, 1926, al@- though it isevident that the improved supplemental propelling means may be utilizedin an equally eiective manner With mining apparatus of various othertypes. This mining apparatus generally comprises a frame l supported onadjustable front and rear supports 2 and 3 respectively hereincomprising sivingable arms and supported on truck Wheels l adapted torun along a usualy mine trackvvay 5. As described in the above mentionedcopending application, the supports 2 and 3 may be adjusted. eithersimultaneously or one independently of the other to eect adjustment ofthe frame l into dilferent elevated positions relative to the trackwayorto be .tilted about a transverse axis to change its angle relative tothe horizontal as conditions may require. Mounted on the frame l forrotation about a longitudinal axis Within spaced bearing means 6 and 7supported by the trames of the front and rear adjustable supports 2 and3, respectively, is a frame or body 8. This body houses a motor 9 andsupports at its forWardend adjustable lierf cutting mechanism l0including a yusual svvingable cutter bit carrying cutter bar. As thespecilic construction of the mechanism for rotating the machine body,for adjusting the cutting mechanisnnand for driving and CTI operatingthe cutting` mechanism do not enter into this invention, furtherdescription of the same is thought unnecessary. The motor 9 also drives,as hereinafter described, the truck Wheel driving mechanism generallydesignated 11 and the improved supplemental propelling means generallydesignated 12. lillectricall energy is conducted to the electricalapparatus of the motor 9 through a usual 'flexible conductor cable 13Wound upon a cable reel 14 mounted for rotation on the rear end of theframe 1 and this reel is also driven as described in the above mentionedapplication from the motor 9.

NOW referring to the truck Wheel driving mechanism 11 it will be notedthat the armature shaft of the motor 9 see Fie'. 3 drives an alinedshaft which has secured thereto as by a key 21 at its rear end a spurpinion 22. As illustrated, the pinion 22 meshes With a spur gear 23suitably secured to a longitudinally extending` shaft 24. Also securedto this shaft is a spur pinion 25 meshing With a spur :gear 26 securedto a longitudinally eX- tending shaft 27. These shafts are suitablyjournaled Within a transmission housing` 28 suitably secured tothe frame1 and have secured thereto as by keys 29 Worms 30 and 31 respectively.These Worms mesh respectively With coaxial fast and slow speed WormWheels 32 and 33 suitably journa'led on anti-friction lbearings 34supported by a horizontal transversely extending shaft 35. rllhis shaftis in turn journaled Within anti-friction bearings 36 support-ed Withinthe transmission housin0i28 and the ivorm Wheels 32 and 33 arealternatively connectible to the shaft by means of friction discclutches 37 and 38 respectively vso .that when the clutch 37 isappliedthe shaft 35 may be driven from the m'otor9 at ya relatively fastspeed While When thefriction'clutch 38 is applied and the clutch 37 isreleased, the shaft 35 may be driven in thesame direction vat alrelatively low speed.

:In 1theipresent construction, secured as by a key 40 to the shaft 35 isa bevel Ypinion 41 meshing` with reverse bevels 42 and 43 suita- Vblyjournaled on anti-friction bearings 44 ,supported by Ia longitudinallyextending shaft 45, in turn journaled Within suitable anti-frictionbearings 46 supported Within the transmission rhousing- 28. Thesereverse Abevels-42 43 are alternativel `connectible'to :acoupling- 49 tothe shaft 45 is an allined shaft y5Ojournaled at its forward end Withinan anti-'frictionbearing51 supported bythe frame 152 of the lrearsupport 3. key 53 to the forward end of the shaft 5() is 'abevelpinion54meshing with a bevel gear Secured as by a 55irotatably supported by atransversershaft 63 to a transverse shaft 64. Also secured to this shaftis chain sprocket 65 which is connected by an endless chain connection66 to a chain sprocket 67 secured to the rear truck vWheel axle 68. Alsosecured to the shaft 64 is a chain sprocket` 69 connected by an endlesschain connection Z'O (see Fig. 2) to a chain spr cket 71 secured to atransverse shaft 72. This shaft is connected by a chain :and sprocketconnection 'l' 3 to the front truck Wheel axle' 7 4. lt will thus beseen that When the clutch device 58 is in a position to connect thebevel gear 55 to the shaft 56 and one or the 'other of the clutches 47,48 and 37, 38 are applied, the truck Wheels may be driven in either ofoppositedirections from the motor 9 at either a relatively hightransport speed or at a `relatively slow cutting speed. lt Will hereinbe noted that secured as by a key Y 6 to the shaft 35 is a bevel pinion7K7 meshing with reverse bevels .7 8 and 79, these bevels beingalternatively connectible by friction clutches 8O vand 81 respectivelyto a longitudinally extending shaft 82. rlhe shaft 82 drives, in amanner clearly described in thc above mentioned copending application,the mechanism for adjusting the supports 2 and 3. As this mechanism`does lnot specifically enter into this invention, description of thesame` is herein thought unnecessary. rlllhe operating means for vtheclutches 37, 38, 47, 48, 58, 8O and 81 are also substantially the sameas those described in the above mentioned Holmes ap- .plicationrllheimproved supplemental propel-ling mechanism 12 for propelling theapparatus along the mine trackway includes haulage devices `83' and 84,yherein each comprising a Winding,` drum 85 and these drums have Wound:thereupon haulage `cables 86 and 87 respectively. Asrthe Vmechanismsfor driving the drums 85 are similarin construction, a description ofone Will sufiice for both. Refer- .ring'to the driving-mechanism for thedrum 85 of the hauling device 83, it Will be noted that meshing` vwiththe reverse bevels 42, 43 is a bevel gear 86 secured as by a lkey 8,7 toa horizontal Vtransversely extending shaft 88 herein alined 'with theshaft 35. rlhis shaft l88 is suitably journaled 'Within' a bearing'sleeve 89 supported .within a br-zaring` bracket 90 secured as by screws91 to one side of the transmission housing,r 28. Connected to the shaft88 is a series of clutch plates or discs 92 which are interleaved With acorresponding series of clutch plates or discs 93 secured to a sleeveportion 94 preferably formedV inparatus at substantially the same speedtegral with the drum. AThe drum 85 is journaled on spaced anti-frictionbearings 95 supported by the bearing bracket 90. In the presentconstruction, the mechanism for applying the clutch 92, 93 comprises ahand wheel nut 96 threadedly connected at 97 to the reduced threaded endof the shaft 88. Surrounding this shaft is an annular pressure plate 98having inwardly pro] cting fingers 99 engaging the adjacent end disc ofVthe clutch. Interposed between the hand wheel 96 and the pressure plate98 is a ball' thrust bearing 100. The hand Wheel for operating thefriction clutch controlling the winding drum 85 f the haulage device 84is indicated at 101. It will thus be seen that when the friction clutch92, 93 isi-applied, the winding drum 85 may be rotated in a direction towind in its cooperating cable at either a relatively slow speed or arelatively high speed, depending upon which of the fast and slow speedcontrolling clutches 37 and 38 is applied. It will also be evident `thatby reversing the motor 9 the winding drums 85 may be rotated in adirection to pay out their cooperating cables at either a relativelyhigh speed or a relatively low speed. When the drums are being driven ata relatively slow speed the cables are drawn in or wound in to propelthe apas that effected by the truck wheel drive, it being evident thatthe apparatus may be propelled along the mine trackway at a relativelyslew cutting speed under the propulsion of either or both the truckwheel driving mechanism 11 and the supplemental haulage mechanism l2.

The operation of the improved mining apparatus will now be described.The apparatus may he propelled about the mine at a relatively hightransport speed under the control of the fast feed control clutch 37 andthe friction clutch 47. The truck wheels are driven from the motor 9 ata fast transport speed through the spur gearing 22, 2 3, worm gearing30, 32, bevel gearing 41, 42, shafts 45, 50, bevel gearing 54, and thechain and sprocket connections 61, G6 and 70. If it is desired to propelthe-apparatus along the mine trackway in a reverse direction at arelatively high speed, the friction clutch 47 is released and thefriction clutch 48 applied, and as a result, the truck wheels are drivenin the reverse direction. During the cutting operation, the cuttingmechanism is operated to cut a kerf beneath the coal and the sumping andwithdrawal cuts are effected by proelling the apparatus bodily along themine trackway at a relatively slow cutting speed. The relatively slowspeed drive of the truck wheels for propelling the apparatus forwardalong the mine trackway is effected by the motor 9 through transmissiongears 22, 23, 25, 26, worm gearing 31, 33, bevel` gearing 4l, 42,friction clutch 47, shafts'45, 50, bevel gearing 54, 55 and chain andsprocket connections 61, 66 and 70. The apparatus may be propelledrearwardly along the mine trackway simply by releasing the frictionclutch i 47 and applying the reverse friction 48, thereby effectingreversal of the drive. If, for any reason, the truck wheels sliprelative to the track rails and their tractive effort is insufficientfor propelling the machine along the mine trackway during the cuttingoperation, the truck wheel driving mechanism may be supplemented by theimproved sup-- plemental propelling means 12. When it is desired topropel the apparatus by means of either of the haulage devices 83, 84the feed cable is unwound from the drum and eX- tended to a point inadvance of the machine as, for instance, anchored at its free end asshown in Eig. 1 to a roof jack or other suitable anchoring device. If itis desired to wind in the feed cable at a speedfappropriate to effectpropulsion of the machine at a cutting speed, the friction clutches 38and 92, 93 are applied, thereby effecting rotation of the drum 85 inwinding direction at a relatively slow speed. The winding drum may beoperated to wind in the cable to eifect propulsion of the apparatusalong the mine trackway in the reverse direction simply by extending thecable in a rearward direction and anchoring the free end thereof to aroof jack or other suitable anchoring device located at the rear oftheapparatus. It will also beevident that if desired the apparatus may bepropelled along the mine trackway in either direction under the'propulsion `of'both the haulage devices 83 and 84. These haulagedevices 83 and 84 may also be utilized for propelling the apparatusupwardly along a steeply inclined trackway or under certain conditionsto be utilized as a safety device for controlling movement of theapparatus downwardly along a steeply inclined trackway. lt will also beevident that these improved haulage devices may be operatedsimultaneously with the truck wheel driving mechanism to supplement thetruck wheel drive in case the truck wheels slip relative to the trackrails or 1f desired, the haulage devices may be used to propel themachine Wholly independent-ly of the truck wheel drive. These haulagedevices may also be utilized for spotting mine cars and for hoistingmine props orany other auxiliary work, thereby obviating'the necessityof providing a separate haulage device for these purposes.

As a result of this invention it will be noted that an improved miningapparatus vof the ,wheel mounted type is provided having improvedpropelling means. It willfurther be evident that by providing thesupplemental propelling mechanism in a mining machine of the wheelmounted universal type, it is possible to supplement the truck wheeldrive in case thetruck wheels slip relative to the track rails, forinstance, When the machine eifecting its vsumping and Withdrawal cuts ormoving along a steeply7 inclined tracliway. It Will still further benoted that the improved winding devices may be utilized for auxiliaryhoisting purposes, thereby cbviating the necessity oit a specialhoisting device. It Will also be noted that the improved supplementalpropulsion mechanism may be embodied in a mining apparatus of a standarddesign With a minimum ot change and expense. These and other uses andadvantages of the improved mining apparatus will be clearly apparent tothose skilled in the art.

While there is in this application specifically described one form whichthe invention may assume in practice7 it Will be understood that thisform of the same is shovvn for purposes of illustration and that theinvention may be modified and embodied in various other forms Withoutdeparting from its spirit or the scope of the appended claims.
